This article discusses how researchers have experimentally recreated a foundational quantum model, the Heisenberg alternating spin chain, using nanographene structures known as Clar’s Goblet molecules. Collaborating with scientists from the International Iberian Nanotechnology Laboratory and Dresden University of Technology, the team linked these carbon-based molecules on a gold surface, achieving a controllable chain of electron spins. This configuration enables manipulation of individual spins, providing insights into quantum interactions that are typically only theoretical. The successful implementation demonstrates nanographene’s potential to serve as quantum “building blocks” and paves the way for creating complex quantum systems, advancing both theoretical and practical quantum research.
